Full Changelog: v4.0.0-alpha3...v4.0.0-beta1.3

v4.0.0 Alpha version 3

From the CHANGELOG:

• (build) Compiles to dist/ko.js
• (build) The dist/tko.js (that exported tko) has been deprecated/removed
• (internal) Add the ES6 LifeCycle class (see tko.lifecycle)
• (binding handlers) Add new-style ES6 Binding Handler class (see custom-bindings documentation and tko.bind/src/BindingHandler.js), descended from the LifeCycle class
• (lifecycle) Fix error with event handler type
• (provider) Add & document the Provider base class
• (subscribable) Add the once, then, when, yet, and next functions
• (parser) Fix early-out for logical (&& / ||) operators
• (binding) ko.applyBindings now returns a Promise that resolves when bindings are completed
• (attr) Support namespaced attributes with attr binding #27
• (options) Add the options.Promise, so users can use a their own or a safe Promise variant of A+/Promises (defaults to window.Promise)
• (attribute-interpolation) Fix interpolation of styles attribute (e.g. style="color: {{color}}") in the AttributeMustacheProvider, by adding attributesBindingMap parameter.

Alpha One

This is the second alpha of TKO.

It incorporates a number of changes, fixes a number of edge cases (particularly with the parser), and incorporates the last pre-release binding plugin, fast-foreach.

• Fix negation operator (-) application - integers/floats e.g. -1 work, as well as variables -x and expressions -(x + y)
• Use tko.binding.foreach for the foreach binding (based on brianmhunt/knockout-fast-foreach)
• Add each as an alias of foreach
• Parser
  • Correct behaviour with dereferencing members of expressions (e.g. (x || y).z or (abc || {x: null})['x'])
  • Fix canonical (() => ...) lambdas
  • Support C & C++ style comments (knockout/knockout#1524)
  • Fix filter/or ambiguity on pipe |
  • Raise an error with anonymous functions
  • Fix && and || operator precedence
• Updated Rollup - changes order of compilation, smaller output
• Fix issue with first rendering of an elseif binding
• Make the template binding expose a conditional for else-binding
• Expose ko.dependencyDetection
• Make sure obj.x uses this of obj where x is a function (e.g. click: model.onClick has this of model)
• Ensure obj.x only uses obj as this when x is a prototypal method (and not just a value)
• Honour explicit references to this (as $data)
• Ensure bindings with multiple filters work as expected
• If available, use a WeakMap for DOM node data (resolves knockout/knockout#2141)
• Fix filters not separated by whitespace (e.g. value|filter1|filter2)
